- a coupling element without contact such as an induction loop, a radio antenna or an optical coupling device connected by a connection embedded in the card to an interface generally contained in the integrated circuit.
- FR-A-2 726 106 discloses an integrated circuit card with the Characteristics of the preamble of claim 1.
- the present invention is defined by claim 1.
- the integrated circuit card with connection mixed is made from an element contactless coupling in the form of a antenna 1 carried by a support sheet 2 and a module, generally designated in 3 including (see Figures 4 and 5) a support film 4 equipped with conductive pads 5 connected to an integrated circuit 6 by wires 7 to ensure connection with contact, and conductive pads 18 connected to the integrated circuit 6 by wires 19 to ensure the connection with a contactless interface included in the integrated circuit 6.
- Integrated circuit 6 and the wires connection 7 and 19 are embedded in a block of resin 8.
- the antenna 1 has two adjacent ends to each other forming an element connection circuit of contactless coupling that the antenna constitutes with the conductive pads 18 of the module.
- this link circuit will be made by conductive tracks extending analogously on a support sheet.
- the link circuit will be by example consisting of copper tracks produced according to the traditional printed circuit technique.
- connection pads 11 are formed on the ends antenna and protrude from the ends of the antenna (see Figure 2).
- the studs of bond they can be made by screen printing of a conductive polymer or by mechanical deposition of a drop of metal. They can also be produced in the form of an electrolytic deposit, by sticking (with an adhesive conductive) or by soldering a metal stud on the printed circuit board, or by chemical attack or mechanical machining of a thick track.
- connection pads 10 for example a conductive material comprising a polymer containing conductive grains, projecting from one side of the support film 4 opposite to the contact pads 18.
- connection pads 10 for example a conductive material comprising a polymer containing conductive grains, projecting from one side of the support film 4 opposite to the contact pads 18.
- connection pads 10 for example a conductive material comprising a polymer containing conductive grains, projecting from one side of the support film 4 opposite to the contact pads 18.
- this is preferably in a plastic state before incorporating the integrated circuit card module according to the invention.
- the holes 9 in the support film of the module are made according to a provision allowing their comparison of connection pads 11 when the integrated circuit module 3 is implanted in the map.
- the support sheet 2 of the antenna 1 is made of a reinforced synthetic material, for example an epoxy resin reinforced with glass fibers or polyester fibers and the antenna 1 is made in the form of a printed circuit on the support sheet 2.
- the support sheet 2 has an opening 12 having a transverse dimension D greater than the transverse dimension d of the resin block 8 containing the integrated circuit 6 (FIG. 5).
- the support sheet 2 of antenna 1 is first of all covered on both sides with sheets of insulating material 13.
- Sheets of thermoplastic material such as PVC are for example applied to the support sheet 2 by hot rolling of so that the sheets of insulating material 13 adhere to the support sheet 2 and fluent for uniform filling the opening 12 in the support sheet 2.
- the material filling the opening 12 furthermore ensures an embedding of the support sheet 2 in the mass of thermoplastic material formed by the softening of the leaves 13. We thus obtains the sandwich structure shown in section in figure 2.
- a cavity generally designated at 14 is then dug into the card body thus formed (figure 3).
- the cavity 14 has a central part 15 of small diameter but deep depth intended for receive the resin block 8 from module 3, and a part device 16 of larger diameter and smaller depth intended to receive the support film 4 and the conductive pads 5 of module 3.
- the height of the connection pads 11 is provided so that during the production of part 16 of the cavity 14 the 11 connection pads of the antenna open into the bottom of the cavity.
- the realization in the support sheet 2 of an opening 12 having a dimension transverse greater than the transverse dimension of the block of resin from module 3 allows the cavity to be produced in a mass of homogeneous material, which makes it possible to use a tool particularly suited to this material.
- the homogeneous thermoplastic material which surrounds part 15 of the cavity embeds the edge of the opening 12 of the support sheet 2, which ensures better resistance of the card to the efforts to which it is submitted during the various manipulations whatsoever during manufacture or during use.
- the sheets 13 preferably have specific thicknesses so that after rolling the antenna 1 is in the vicinity of the neutral fiber of the card. This avoids phenomena of bending of the card body resulting from expansion differential when antenna 1 is not on the fiber neutral.
- Antenna 1, or the element's connection circuit contactless coupling can also be realized directly on a sheet of thermoplastic material.
- the studs 11 produce an inhomogeneous mass which tends to move to the center of the map as illustrated by the Figure 6 under the effect of pressure on the plastic during creep.
- This deformation causes a increased creep of the thermoplastic material to plumb with the studs 11.
- Leaves spacers 20 are coated with heat-activated adhesive and may preferably be covered with sheets of transparent protection 21.
- module 3 is implanted in the card, for example by placing in the bottom of the cavity a small amount of glue 17 which spreads between the resin block 8 and the wall of the cavity 14.
- glue 17 which spreads between the resin block 8 and the wall of the cavity 14.
- the conductive material 10 arranged in the holes 9 of the support film 4 crashes as illustrated in Figure 5 and ensures contact with the connection pads 11, thus forming a conductive member between the conductive pads 18 and the antenna 1.
- the conductive material 10 When the conductive material 10 is in a plastic state before the installation of the module, we preferably provides after hardening in temperature of the conductive material in order to ensure a superior connection reliability.
- the conductive pads 18 which are connected to the ends of the antenna although they are turned towards the outside of the module, i.e. on a face opposite to the integrated circuit 6, may not be used to make contact with a machine.
- the conductive pads 18 which are connected to the antenna only then serve to bridge the ends of the antenna and the corresponding wires 19.
- Figure 7 illustrates a second example wherein the conductive pads 18 serving as bridging between the integrated circuit 6 and the ends of the antenna are this time arranged on the face of the film support 4 carrying the integrated circuit 6.
- the module preferably comprises directly above the conductive pads 18, holes 22 which allow a heating tool to come into contact with conductive pads 18 during installation of the module.
- the connection pads 10 and the connection pads 11 which are used to connect the conductive pads 18 to the ends antenna 1 are then advantageously made in fusible conductive material, for example a material conductive comprising metallic grains having different melting points as described in the document FR-A-2.726.001, which allows a hot and get a bond with resistance particularly weak electric between the ranges conductive and antenna.
- the module is fixed by a bead of glue 23 placed in the bottom of part 16 of cavity 14 by interrupting it at vertical to the connection pads 11.
- connection mode can also be performed by depositing a drop of conductive polymer on the end of stud 11 appearing at the bottom of the cavity before fixing the module in the cavity.
- the conductive pad 18 is not provided with a connection pad 10.
- grooves are preferably made at the bottom of part 16 of the cavity, as illustrated by FIG. 8 which is a top view of the cavity before the installation of the module.
- Gorges 24 are made straddling the ends of the studs 11 and grooves 25 are made of on both sides of the gorges 24.
- the depth of the gorges 24 and 25 is adapted to the nature of the products which are used so that the facing surfaces are properly wetted by the corresponding products during the installation of the module. Especially when the material conductive is fixed on the contact pads of the module it is important that the grooves 24 are deeper than the grooves 25 so that the conductive material does not no obstacle to bringing the parts of the module into contact glue look.
- Figure 9 which is a partial sectional view of the card at the link between the module and the connection circuit of the contactless coupling element illustrates a variant of this embodiment.
- the conductive pad 18 is carried by the external face of the support film 4 which then has holes opposite the pads 11.
- a conductive pad 26, rigid or in thermoplastic material, is fixed in the holes of the film and is surfaced so that its underside is flush with the surface bottom of the film.
- the connection between pad 26 and the pad 11 is provided by a drop of thermoplastic material 27.
- Figure 10 illustrates another variant in which the connection between the conductive pad 18 and the stud 11 is provided by an elastic conductive insert 28, for example an elastomer insert made conductive in the mass or covered with a conductive film or conductive powder.
- an elastic conductive insert 28 for example an elastomer insert made conductive in the mass or covered with a conductive film or conductive powder.
- Figure 11 illustrates another variant of realization that the support film 4 and the range conductive 18 are drilled with a hole which leads to the external surface of the module.
- a drop of conductive polymer hot-melt or a conductive elastic insert 29 is arranged on the stud 11 prior to the installation of the module. This arrangement allows, after installation of the module, to level off the conductive material which overflows from the hole outside the module. It is also possible to introduce conductive material (in solid or pasty form) in the hole after mounting the module on the card.
- Figure 12 illustrates a third example in which the antenna 1 is no longer carried by a backing sheet in epoxy resin sandwiched between two thermoplastic sheets but is directly made on a thermoplastic sheet that is enough to cover on the side comprising the antenna with a sheet of the same kind to obtain a card body in homogeneous material.
- connection between the conductive pad 18 and the antenna 1 is provided by rigid conductive members, here a screw 30 which crosses the conductive surface 18 and the end antenna 1.
- the organ conductor is put in place after fixing the module in the card cavity.
- Figure 13 illustrates an alternative embodiment in which this embodiment of the connection by a rigid member passing through the layers to be connected is used in connection with an antenna 1 equipped with a pad connection 11 projecting from the antenna. This increases the contact surface between the screw 30 and the end of the antenna forming the link circuit with the antenna.
- Figure 14 illustrates an embodiment of the invention according to which a conductive member is introduced into a hole opening on the surface of the card and crossing the antenna without it having been previously equipped a connection pad 11.
- the module is set up place before binding as in the case of Figures 12 and 13 then a hole 31 is made through the part of the module and the card part overhanging the end of the antenna, and through this end, that is to say that the holes 31 pass through the connection circuit and the associated conductive pads 18.
- the hole thus made is filled with a conductive material which can either be a rigid insert of corresponding shape forcibly inserted or held by a helical thread, a material conductive introduced in a pasty state, i.e. an association a rigid insert with a pasty material, either another conductive elastic material.
- the hole 31 is conical. This shape has the advantage of increasing the contact surface of the conductive connecting member with the conductive pads that he crosses. In particular, given the very thin thickness of the different layers crossed there is possible to industrially make a conical hole having an apex angle of 120 ° C, which multiplies by two the contact surface with the crossed layers.
- a conical hole allows inspection visual of the quality of the hole made with a simple camera to ensure in particular the absence of shavings and the surface condition of the conductive layers crossed.
- a conical hole or more generally a blind hole having an increasing section from the bottom of the hole up to an opening thereof, allows filling easier than with a cylindrical hole and ensures self centering of the inserted conductive material, either rigid or pasty which increases the tolerance on the positioning of the installation tools conductive material.
- the conductive material When the conductive material is pasty, can use a material already conductive in the pasty state or a material made conductive by heating or after polymerization.
- FIG. 15 illustrates an alternative embodiment of this type of bond.
- the hole 31 is cylindrical and the conductive material filling the hole is a combination of a material conductive 33 introduced in the pasty state and an insert rigid 34 introduced into the pasty material.
- This solution combines the advantages of the low resistivity of the insert rigid and good contact of the pasty material with all exposed surfaces.
- Figure 16 illustrates another type of connection according to one embodiment of the invention consisting in making a hole 35 in the body of card and through the end of antenna 1 after the realization of the cavity 14 but before mounting the module then insert a conductive connecting member into this hole.
- the hole 35 is conical and the connecting member is under the form of a block of material which has been introduced in the state pasty then polymerized and which is slightly protruding by compared to the bottom of the cavity, over a thickness (which can be controlled by machining) substantially equal to the thickness adhesive used to fix the module in the cavity.
- the bringing the pad 36 into contact with the conductive pad 18 of the module You can also apply a heat punch to plumb with pad 36 in order to perfect its connection with the conductive pad 18. It is also possible to produce this type of connection by having an elastic conducting member in the hole 35.
- Figure 17 illustrates a variant consisting in fixing a rigid insert, here a screw 37 in the bottom of the cavity 14 so that the insert 37 passes through the end of the antenna 1 and extends slightly projecting from the bottom of the cavity, then at cover the projecting part with conductive material 38 in order to make good contact with the conductive pad 18.
- Figure 18 shows an example using anisotropic adhesive 39 to secure the module in a cavity into which a connecting stud opens 11 associated with one end of the antenna then to submit the adhesive at a pressure located directly above the stud connection 11 in order to make the corresponding part conductive 40 of adhesive 39. While using a bead continuous anisotropic glue or a washer of adhesive anisotropic which ensure a homogeneous fixing of the module, it is thus possible to obtain a localized conduction.
- FIG. 19 illustrates an embodiment of the invention in which the hole 41 passing through the card body and the end of the connection circuit has a spherical cap shape, or more generally a concave curvilinear section (which could be in the form of a paraboloid or ellipsoid.
- a shape delimits a larger volume than a conical hole which allows to increase the tolerance on the volume of the drop of conductive material 42 which is introduced into the hole while maintaining a bond satisfactory between the link circuit and the range associated driver 18.
- Support sheet 2 and cover sheets 13 are preferably produced in the form of a strip continuous, possibly provided with lateral perforations not shown, in order to make a series of cards by sequential movement of tapes at workstations successive.
